Property change demo

comes from TestPropertyChangeActivity

public class TestPropertyChangeActivity extends BaseActivity {

    @BindView(R.id.tv_desc)
    TextView mTv_desc;

    @BindView(R.id.bt_set_text_on_TextView)
    Button mBt_changeProperty;
    @BindView(R.id.bt_set_text_on_mediator)
    Button mBt_temp;

    DataMediator<StudentModule> mMediator;


    @Override
    protected int getLayoutId() {
        return R.layout.ac_test_double_bind;
    }

    @Override
    protected void onInit(Context context, Bundle savedInstanceState) {
        mBt_changeProperty.setText("click this to change property");
        mBt_temp.setVisibility(View.GONE);

        //为数据模型创建  中介者。
        mMediator = DataMediatorFactory.createDataMediator(StudentModule.class);
        //添加属性callback
        mMediator.addDataMediatorCallback(new DataMediatorCallback<StudentModule>() {
            @Override
            public void onPropertyValueChanged(StudentModule data, Property prop, Object oldValue, Object newValue) {
                Logger.w("TestPropertyChangeActivity","onPropertyValueChanged","prop = "
                        + prop.getName() + " ,oldValue = " + oldValue + " ,newValue = " + newValue);
                mTv_desc.setText(String.valueOf(newValue));
            }
        });
        mMediator.getDataProxy().setName("heaven7");
    }

    @OnClick(R.id.bt_set_text_on_TextView)
    public void onClickSetTextOnTextView(View v){
        mMediator.getDataProxy().setName("time: " + System.currentTimeMillis());
    }
